EFFECT OF COEFFICIENT OF LATERAL PRESSURE OF STUFFING-BOX GLAND WITH SOFT STUFFING ON SERVICEABILITY OF SEALED COUPLING

摘要

Deformation of stuffing, which indicated that the load on its internal perimeter exceeds that on its external perimeter, is analyzed. Expressions are presented for recalculation of the coefficient of lateral pressure when its value obtained for one section of the stuffing is related to the value required by the other section. Application of this computational procedure will permit a reduction in wear of the stuffing and loss of thickness due to friction of the part being sealed against the stuffing with retention of a given degree of airtightness of the sealed coupling.
